How do you call the screen at the back of a chair?

I need to write a piece involving "the screen at the back of a chair". I'm wondering if there's a more professional term for it. The whole sentence is:

"The new barrier-free cinema is now equipped with... screens at the back of the chairs to provide subtitles for people with partial sight"

I feel that "screens at the back of the chairs to provide subtitles" is a bit wordy. Any suggestion to reduce the number of words (e.g. if there's a more professional term for the equipment, as mentioned)

In the aircraft I'm familiar with, they're called personal TVs or personal televisions. But I can see if you want a name that indicates they are for subtitles only, you might like subtitle screen (subtitles screen, with two "s" together, gets a little awkward, and subtitling screen sounds too much like a screen a subtitler might use).

Added: Sorry, I should have waited for clarification, but I imagine they are on the seat back in front of you.

Further addition: Since this is a new technology, I like the explanation of the original and don't feel you should be creating a name that people will have to figure out.

Yes, it's on the back of the chair in front of you, similar to the ones you watch on planes? Google didn't generate any professional terms for me either. So I think it's up for me to invent a grammatically correct phrase for it. That's why I need your help!

How about, "The new barrier-free cinema is now equipped with... extra subtitles display on the back of the chairs..." (I use extra as other subtitling equipment has been mentioned in the earlier omitted part of the sentence.

The new barrier-free cinema is now equipped with a subtitle display screen on the back of the set in front of you.

I didn't see the earlier suggestions before the previous. (Very slow on my mobile phone.) I suppose what I was thinking of was '... with subtitles on individual screens'. (Are they still 'subtitles' if they aren't at the bottom? Perhaps closed captions?)

Movie theaters ... the airplane reference was to similar screens and what they are called on planes. Since that terminology (personal TV, individual screen, etc.) will already be resident in some people's brains, it makes sense to consider an existing term -- or an adaptation of it -- before we create an entirely new term.

The new barrier-free cinema is now equipped with a subtitle display screen on the back of the set in front of you.

Note that they're called seats, not chairs.

In addition, what is the difference between the usage of seat and chair in this context? I am aware of the thread http://forum.wordreference.com/showthread.php?t=777570 but it doesn't really answer my question.
So seat always refers to the thing you sit on in specific places e.g. theatre, bus etc.?

I think your last line sums it up pretty well -- the only seat I can think of in a home is a loveseat, a specific type of furniture for two people. Everything else is a chair or sofa (or Stratolounger). (Links are to images.)
